You are using a plugin which is not compatiable with that version of AviSynth. As explained here, plugins compiled for AviSynth v2.5 are not compatible with AviSynth v1.0x/v2.0x and vice versa.
You probably installed/registered a version of AviSynth which doesn't contain that specific filter. Make sure that there are no other versions floating around on your hard disk (there's a possibility that a version will be registered while it is not in your system directory). Make sure that the latest stable version is registered, see also here.
Install a codec which supports YV12. DivX5 or one of the recent XviD builds of Koepi or Helix YUV codec or some other (ffvfw, ffdshow). If that still doesn't work, modify your registry as explained in the next question.
This error means that you are using AviSource to open your AVI file, but you don't have an ACM codec to decode the audio stream. The most common problem is that your audio is an AC3 or a MP3 stream, but you don't have the corresponding ACM codec installed. It can also happen that your audio is a "crippled" (that is, with an incorrect header) MP3 [1] [2] [3].
There are several solutions for this problem:
Vid = AviSource("Blah.avi", audio=false)
Aud = DirectShowSource("Blah.avi", video=false)
AudioDub(Vid, Aud) This usually is an indicator of a script error, where the input is actually the error message being displayed. Here, xyz is the length of the error message text and 56 is the height (xyz will vary depending on the error message whilst the height will always be 56 pixels). Your encoder is seeing the error message as an RGB32 input source and hence the error. Opening the script with WMP or VirtualDub should display the error message. Fix the error in the script and retry to encode.
Usually, this error message shows up if you don't have the right VfW codec installed for decoding your video. Get Gspot to find out which codec you need. Get, for example, XviD for your MPEG-4 ASP clips and Cedocida codec for your DV clips. If you have problems finding the right one, ask around on the video forums.
But it can also show up if you call AviSource too many times. The dll for the decompression codec is loaded separately for every AviSource call. Eventually an OS-imposed limit is reached, the codec can't be loaded and you get that error message. More discussion can be found here. A good solution is to use a number of scripts (keeping each below the problematic limit of avi calls) and encode them separately, and join them afterwards in some application.
This is a common error that occurs when DirectShow isn't able to deliver any format that is readable to AviSynth. Try creating a filter graph manually. See if you are able to construct a filter graph that delivers any output that AviSynth can open. If not, you might need to download additional DirectShow filters that can deliver correct material. If you can play the graph in GraphEdit, make sure to remove the video and audio renderers, before saving the graph and opening it in AviSynth. Some examples can be found here.
AviSynth has problems with non-ANSI chars on filenames. It only supports 8 bit character ANSI text. Some discussion about this: [4] and [5].
Access Violation at 0x0, reading from 0x0 is usually caused by running out of memory (memory leak ???). It can be caused by a plugin which is leaking memory, but apparently it can also be caused by other things (codecs, applications ???) [1] [2]. Add SetMemoryMax(...) at the beginning of the script. If that doesn't help, report the issue in the doom9 forums, and we will try to help finding the cause of it.
It means you are passing incorrect arguments (that is of the correct type) to your script, filter or plugin. For example:
# passing a float (2.0), while Loop expects an int: Loop(clip, 2.0)
# passing three clips to Overlay instead of two:
AviSource("anime_raw.avi")
karaoke = AviSource("karaoke.avi")
Trim(0,999) + Trim(1000,1030).Overlay(last, karaoke, mask=sign.ShowAlpha()) + Trim(1031,0)
# last should be omitted as argument to OverlaySo make you the passed arguments are of the correct type and read the corresponding documentation if necessary.
